Vulkan

Optimizing Vulkan for tile-based GPUs? The Vulkan Guide's TBR best practices page is a great resource.

The core idea: keep data on-chip.

Quick wins:
- Set loadOp/storeOp correctly on render pass attachments
- Mark depth/stencil as DONT_CARE if you don't need them after the pass
- Use compact pixel formats to fit more data per tile
- Separate vertex positions from other attributes to speed up the binning pass

New blog: how FFmpeg uses Vulkan Compute shaders to accelerate professional codec workflows — FFv1, ProRes, ProRes RAW, APV and more — on any Vulkan-capable GPU, with no fixed-function hardware required.

Fully GPU-resident, no CPU hand-offs, and portable across the broad Vulkan device ecosystem.
